I don’t see it that way, but okay. And tyranny of majority could be interpreted twofold here: it’s probably a tyranny for the majority against protesters to tell them that they can’t protest at the university, but it’s also tyranny of majority for 10000 protesters to tell 1000 students of a university that they don’t care about their wish to study in peace? No?

Surely if you live in Iran or something just as oppressive, protesting against the government is probably more important than studies and even in the eventual best interests of students. But at that point (as I mentioned), permits and restrictions are irrelevant: go protest without a permit regardless or whatever.
